“…The work environment also has periods of low stimulation (dimmer light, quieter, less bustle) which unmasks a high propensity for sleep in nurses who may be sleep deprived as well as working at the circadian low (Dinges, 1989). Night shift sleepiness produces three problems: (1) reduced alertness and increased risk for involuntary sleep and patient care errors (Dorrian et al, 2006; Dorrian et al, 2008), (2) increased risk of job-related accidents and injuries, including motor vehicle accidents on the drive home from work, (Folkard, Lombardi, & Spencer, 2006; Horwitz & McCall, 2004; Scott et al, 2007; Swanson, Drake, & Arnedt, 2012), and (3) increased risk for long term impaired health, associated missed work and increased health care costs (Horwitz & McCall, 2004; Geiger-Brown, Lee, & Trinkoff, 2012; Geiger-Brown & Lipscomb, 2011). Scheduled naps during night shifts have decreased sleepiness, increased alertness and total sleep time, and improved response accuracy (Ruggiero & Redeker, 2014).…”
